What is one of the key principles of the SRUF regarding the use of force?

One of the key principles of the Standing Rules for the Use of Force (SRUF) is that force should be proportional to the threat faced. This principle ensures that any use of force is not excessive in relation to the threat level encountered. It emphasizes the importance of measuring the response to the nature and severity of the threat, which helps to prevent unnecessary escalation and maintains the ethical standards of engagement. Proportionality acts as a guideline to ensure that actions taken in response to a threat are appropriate and justified, fostering responsible decision-making in the use of force scenarios.

This principle aligns with international law and military doctrine, reinforcing the necessity to retain a balance between security objectives and the minimization of harm to individuals, property, and the overall operational environment.
